Question

the substance that does the dissolving (ex:water)
options: solution, solvent, solute, weathering

Explanation:

To solve this, we recall the definitions of the terms:

• A solution is a homogeneous mixture of solute and solvent.
• A solvent is the substance that dissolves the solute (e.g., water dissolves salt).
• A solute is the substance being dissolved.
• Weathering is the breakdown of rocks, unrelated to dissolving.

So the substance that does the dissolving is the solvent.

Answer:

B. solvent (assuming the options are labeled as A. solution, B. solvent, C. solute, D. weathering; if labels differ, the correct option is the one with "solvent")
